That they had puppies.....
No. Taking a puppy away at such a young age would be severely detrimental to its health and mental development. Puppies need to be fully weaned, and gone through the socialisation stage (which happens around 6 - 8 weeks) with their own littermates, mother, and humans before they can be taken away. Puppies that have left before this time will most likely have socialisation problems later on.
